Method Details

getType

public org.jolokia.server.core.util.RequestType getType()

The type of request which can be served by this handler

Returns:

the request typ of this handler

checkForRestriction

protected void checkForRestriction(org.jolokia.server.core.request.JolokiaExecRequest pRequest)

Check whether there is a restriction on the type to apply. This method should be overwritten by specific handlers if they support a more sophisticated check than only for the type

Specified by:

checkForRestriction in class AbstractCommandHandler<org.jolokia.server.core.request.JolokiaExecRequest>

Parameters:

pRequest - request to check

doHandleSingleServerRequest

public Object doHandleSingleServerRequest(MBeanServerConnection server,
 org.jolokia.server.core.request.JolokiaExecRequest request)
                                   throws InstanceNotFoundException,
ReflectionException,
MBeanException,
IOException

Execute an JMX operation. The operation name is taken from the request, as well as the arguments to use. If the operation is given in the format "op(type1,type2,...)" (e.g "getText(java.lang.String,int)" then the argument types are taken into account as well. This way, overloaded JMX operation can be used. If an overloaded JMX operation is called without specifying the argument types, then an exception is raised.

Specified by:

doHandleSingleServerRequest in class AbstractCommandHandler<org.jolokia.server.core.request.JolokiaExecRequest>

Parameters:

server - server to try

request - request to process from where the operation and its arguments are extracted.

Returns:

the return value of the operation call

Throws:

InstanceNotFoundException

ReflectionException

MBeanException

IOException
